FD3S RX-7 Front Caliper Adapter

This front BBK adapter is a precision-engineered solution for mounting larger performance brake calipers to the factory front knuckle on the FD3S RX-7. It is not a universal bracket or generic conversion — every critical dimension is designed around a known caliper and rotor configuration to ensure proper caliper alignment, pad sweep, and rotor centering.

Machined from 7075-T6 aluminum, bead blasted, and finished in a gloss black anodize, this adapter delivers durability, corrosion resistance, and a clean OEM-plus appearance suited for off-road and competition use.

⚠ This product is intended for off-road use only.
